Religion & racism

The study concludes that religious belief isn't an inoculation against racial prejudice.

Researcher Wendy Wood of the University of Southern California, said religious groups "tend to favor in-group members, who hold similar beliefs ... and because in-group members tend to be the same race, the in-group bias gets tied up with racism."

Wood said only one in 10 U.S. churches have "even a moderate amount of racial diversity."
